What about NLOS (trees and buildings) @ 3km
with a max EIRP of 33db (as that’s what we are stuck with in the UK L) or 28km with good
LOS/Fresnel clearance with max EIRP of 33db?

WRAP vs RB532
Paul,
I haven't tried the Spectra yet but am planning some links with the Link
Estimator. Are you familiar with this tool? You may have to attend a training
session to get access to the partner site and profile generator. However I'd be
happy to generate a path report for you .. the tool is quite good, and at least
the sales people will tell you it's very accurate - if it says 99.999%
reliability, that's what you'll get. Trees and other obstructions can be added
to the profile manually. The single biggest factor is antenna gain .. you just
won't get 200 Mbps over 40 km without 4' dishes on both sides.
Best,
